Relative Humidity Generator

This system automatically generates multipoint profiles as well as manually entered humidity levels while continuously storing and printing system data.

Relative humidity generator.

The rdsa rotary dilution system is specifically developed and patented to allow the relative humidity generator hg 101 to control the relative humidity with high speed and high stability. To address variety of applications multiple sensors and rh control modes can be utilized. The model hg 100 relative humidity generator is a compact portable bench top instrument which supplies a specified constant air or nitrogen flow rate with a manually preset relative humidity. The automatic relative humidity rh generator humisys lf low flow was specifically designed for easy interfacing to other analytical equipment to provide rh controlled stream.

Relative humidity accuracy of 1 0. The hygro mini portable humidity generator calibrator is the smallest unit available with variable control for both humidity and temperature. Relative humidity range of 5 85 relative humidity 23 c. The humisysxr extended range is a customized version of the humisys family of the superior rh generators.

Standard rh 200 has relative humidity range from 3 to 95 for custom rh generators temperature at target instrument can range from ambient to 80 c. The generator is suitable for achieving relative humidity ranging from 10 to 95 with uncertainties of under 1 at ambient temperature and can be used for the calibration of relative humidity instruments in the laboratory and on site. Several modes of rh control are available depending on selection and location of sensors. New series of superior relative humidity rh generators that were deigned for easy interfacing with other analytical instruments that would benefit from carrying out measurements at precisely controlled rh conditions.

Flow rates of usually up to 500cc min are used. The 1200 will automatically supply relative humidity dew point frost point and other calculated values for instrument calibration and evaluation as well as precision environmental testing. Indeed the response time for a ramp from 20 to 80 is performed in 30 seconds. Reaches the level the stability of the measurement is better than 0 2 rh.

Flow rates of 50 100 200 or 500 cc min are available at the same cost. The purpose of this instrument is to provide large rh range of humidiied stream from very low to high water vapor concentration to the user defined location. Temperature range of 18 c to 35 c. Orientation does not affect accuracy.

This unit was designed for field calibration. The hg 100 easily integrates with a variety of target systems laboratory instruments such as x ray diffractometers tga tma dma calorimeters and micro calorimeters as well as glove boxes and environmental chambers. The concept and design of a miniaturized two pressure humidity generator are presented. Any programmed set point can be reached within three minutes.

Controls range of both temperature humidity.
